COIN-FREED APPARATUS.

SPECIFICATION forming part of Letters Patent No. 640,202, dated January 2, 1906.

Application filed April 6, 1898. serial No. 676,702. (No model.)

T0 ctZZ whom it may concern.-

Be it known that I, GERsoN IGERSHEIMER, a subject of the Emperor of Germany, and a resident of Frankfort-onthe-1Vlain, Germany, have invented certain new and useful Improvements in Coin Freed Apparatus, of which the following is a specification.

This invention relates to improvements in coin-controlled apparatus for securing various articles, such as clothing or bicycles, in place.

The object of the invention is to'provide a device that may be operated either upon the insertion of a coin therein or the manipulation of an operating-key in the hands of authorized persons.

The invention has for its further object to produce a device of this nature which may be unlocked by the manipulation of a second key and also the provision of means whereby the unlocking-key is retained in the device while it is unlocked and released when the device is locked.

A further object is to provide means for retaining the operating-key in the device while it is locked and for releasing it when the device is unlocked.

To accomplish these ends, there are provided two normally-independent cams, with their dependent mechanism, a locking-arm for securing the articles in place, and a bolt for engagement with said cams to make them coactive and thereupon permit the lockingarm to be operated. These cams are also adapted to be connected by a coin to accomplish the same result. In combination with these parts are others, to be hereinafter described, which cooperate to produce the other objects of the invention.

Of the accompanying drawings, Figure 1 is a side View of the apparatus. Fig. 2 is afront side view of the device with the cover removed, showing the position of the mechanism when the device is unlocked. Fig. 3 is a similar View, the devicebeing locked. Fig. 4 is an elevation of the coin-chute-engaging disk. Fig. 5 is an elevation of the engaging stop-disk. Fig. 6 is an elevation of the connection bearing-disk. Fig. 7 is an elevation of the bevel-arm. Fig. 8 is a front side View of a part of the an xiliary bolt, and Figs. 9 and 10 are plan views of opposite faces of the bolt. Fig. 11 is a detail view of aspecial key;

The cover of the device is shown at A, and B denotes the base-plate. An angular plate 5 is secured to the base B, and its upright part has a circular perforation to serve as a bearing-support for a rock-shaft 11, which is journaled at its other end in a similarly-perforated angular plate 6, which is also secured to the base B. The rock-shaft carries at one end a manually-operable locking-arm E. Secured to the rock-shaft 11, between the supports 5 and 6, is a cam F, (shown in detail in Fig. 4,) provided with a hub 12, which carries a slot 13. The cam F is also formed with a circular perforation 14, a shoulder 15, and an engaging notch 16. A coil-spring 17 sur rounds the rock-shaft 11, having its ends secured in the support 5 and rigidly secured to camF and forcing the locking-arm E to remain normally at the extreme limit of its open position. A second cam G is mounted upon the rock-shaft 11, but not secured thereto, contiguous to the cam F. Cams F and G do not normally coact, but are adapted to be connected for simultaneous operation. The cam G, as shown in Fig. 5, has a series of formations which register and coact with corresponding parts of the cam F, viz: Coin-slot 18 regis- 11ers with slot 13, engaging notch 19 registers with notch 16, stop 20 coacts with the shoulder 15, andperforation 21 registers with perforation 14 of the cam F. The cam G is also provided with a square shoulder 43.

An angular plate 7 is secured to the base B, having its ends bent up to form bearing-supports 8 and 9 for a locking-bar K. The locking-bar is formed with :1; lug 31 at one end, adapted to bear along the periphery of the cam the cams G and F when the apparatus is locked. A coil-spring 33 is mounted on the locking-bar K, between the supports 8 and 9, bearing With one end against the support 9 and with the other against a collar 34, mounted on the locking-bar and held by a dowel-pin 35. The spring 33 maintains the locking-bar K with a constant pressure upon the periphery of the cam G. Inclined grooves 36 are milled out on both sides of the locking-bar K at a.

G and to engage in the notches 19 and 16 of convenient part of its length, Figs. 8, 9, and

10, and on one side is left a shoulder 37 for retaining the key in the device.

An angular retaining-plate L (shown in detail in Fig. 7) is secured to the locking-bar K and is beveled sharply at two of its edges 38.

Angular plates 22 and 23 are secured to the base B, and their uprights are adapted to serve as supports for a key-operated reciprocating rod H. This rod H is formed with a cylindrical portion 24 and a rectangular portion 25,the latter servingas a bearing-shoulder for a coil-spring 26, which surrounds the cylindrical portion 24 and bears with its other end against the supporting-plate 23. Inclined grooves 27 are milled out from both sides of the rectangular part 25,and a shoulder 28 is left for retaining the key. This construction is similar to that upon the lockingbar K and is shown in detail in Figs. 8, 9, and 10.

A rotatable cam I (shown in detail in Fig. 6) is mounted on the end of the reciprocating rod H, and this cam carries a projecting pinbolt J, which is always engaged in the perforation 21 of the cam G and is adapted on the reciprocation of the rod H to pass through the perforation 14 of the cam F to adapt the cams F and G for coaction. Owing to the constant engagement of the pin-bolt J in the perforation 21 the cams I and G will always rotate simultaneously. The cam I, as shown in Fig. 6, is cut away to form two sides 30, the edges of which are beveled sharply to adapt them for engagement with the beveled edges 38 of the retaining-plate L.

In Fig. 11 is shown a form of key 0 which may be used to operate the reciprocating rod H or the locking-bar K, or both. As shown, it is a metal plate formed with a slot 39, lug 40, and handle-piece 41. When this key is inserted in a key-slot and pressed down, its lower edges come in contact with the ends of the inclined grooves 27 or 36, imparting longitudinal movement to the member in which the grooves are formed. The lug 40 passes under the shoulder 28 or 37, and when the longitudinal movement of the grooved member has carried the open portion of the groove beyond the key-slot the key cannot be withdrawn.

The operation of the device is as follows: When it is desired to control its operation by a coin, the coin is inserted in the coin-slot of the cover A, whence it falls into the slot 13 of the cam F, coming to rest only when it lies partly within said slot and partly in the coinslot 18 of the cam G. The cams are now coactive. When it is desired to control the operation by the bolt, the pin-bolt J is caused to proceed from its normal position within the perforation 21 of the cam G until it is engaged also in the registering perforation 14 of the cam F. The cams are now also coactive. When the key 0 is inserted and pressed downward, it is forced upon the inclined grooves 27 of the reciprocating rod H,

causing the latter to be moved in the direction of the cam G against the tension of the spring 26. The open groove 27 now passes beyond the lug 40,and the key 0 is retained by the shoulder 28 against removal. By this movement of the rod H the cam I also is brought into engagement with the retainingplate L, the beveled edge 30 of the cam acting with the beveled edge 38 of the plate to force the latter to one side against 'the pressure of the coil-spring 33 on the bar K. The cam is permitted by this movement of the plate to pass beyond the latter, when immediately the plate,under pressure of the spring 33, resumes its original position and prevents the reciprocation of the rod under pressure of the coil-spring 26. Furthermore, with this movement of the rod H the pin-bolt J is pushed through the perforation 14 of the cam F, thus locking the cams F and G together, making them coactive. The position of p the parts at this point is illustrated in Fig. 3. The cam I can never be rotated independently of the cam G, because the pin-bolt J is always engaged in the perforation 21 of the cam G, and the latter is prevented from rotation independent of the cam F, because its stop 20 engages with the shoulder 15 on cam G and its shoulder 43 engages with the lug 31 on the locking-bar K. The locking-arm E is next turned against the pressure of spring 17 until it is engaged with the garmentsupport K. In this movement the cam F is rotated with the rock-shaft 11, forcing with it the cam G by means of the shoulder 15 and stop 20, and hence when the pin-bolt has been forced into engagement with the perforation 14 the cam F forces also the cam I to rotate with it. The cam G bears with its periphery against the lug 31 of the bar K against the pressure of spring 33 until the lug 31 engages in the notches 16 and 19 of the cams F and G, and the parts are locked, and an unlocking-key cooperating with the inclined grooves 36 and 37 may be removed.

When it is desired to unlock the apparatus, the unlocking-key is pressed upon the inclined grooves 36, forcing the lug 31 out of engagement with the notches 16 and 19. The unlocking-key will now be retained, and the locking-arm E being released will be forced back by the spring 17 until brought to rest by the engagement of the shoulder 43 of the cam G with the lug 3].. Reverse operations take place with the remaining parts, and if the pin-bolt has been used to connect the cams it rotates the cam I back to its original position. When the cam I approaches the end of its rotation, its beveled edges 30 come again in contact with the beveled edges 38 of the retaining-plate L. \Vhen the locking-bar K is moved by the cam G, it carries with it the retaining-plate L, the beveled edges of which slide along the beveled edges of the cam I until only their knife-edges are in contact, when the cam I is released, and under pressure of the coil-spring 2b the reciprocating rod H, carrying the cam I, returns to its Original position. By this movement the pinbolt J is withdrawn from engagement with the cam F, the key 0 is released from the shoulder 28, and the parts are again in position to be operated either by the key or a coin.

The invention can be modified in unessential respects to make it applicable to any coincontrolled apparatus, and I do not .limit myself to the described structure.
